The pump looks well put together, the rubber dampners are excellent additions to keep noise down. Im sitting across the living room(10ft) and cant hear it all. Even when im next to the glass i can barely hear a hum when the pump is 100%. I did buy a variable power supply used for laptops plus a dimmable power supply used for leds( hasnt showed up yet).
The w1 mode puts out a great wave. I just havent found the sweet spot for it to really sync up to my tank just yet. The other modes(w2 and w3) i havent really play with those just yet. The else mode is okay but when i chose it, it never cycled to other modes( else mode=random mode) after doing some reading online the control knob on the controller controls how long it takes to cycle the random modes. I had the knob turned all the way down for longest cycle time. Once i figured this out it was lights out time in my tank and i have the controller in my canopy so that the light sensor would work. So its in nite mode right now and will play with it tomorrow.
The suctions cups/magnet are really strong on my 3/8" glass. I even took off the magnet on the outside and the pump was hard to slide across the glass inside the tank.
With the pump turned down to 15volts, in W1 mode(wave mode) with the control knob turned all the way down( off 1 second, on 1second) its blowing all the way across my 4ft tank with a 1"wave.
I havent been able to make a huge wave just yet, as i feel that only happens when the pump is properly synced to the tank size.
I did notice lots of gunk in suspension after turning on this pump and turning off my korlia 4 and 3. So at the moment it is the only pump in my tank except for the 1200gph returns from my return pump.
The only dislike i have so far and is the variable power supply i bought has a short power cable and i had to do some electrical rearranging so it could be plugged in and thats not the wp40's fault.
In a day or two i will have this pump dailed in to my tank and potentially i may buy a wp25 for the other side or maybe another wp40 but for now im 100% pleased with the price,shipping,controller,powersupply and the pump.
